This invention relates to telephones of the automaticY type and itprovides efficient and reliable means whereby the correct chargeablenumber of calls made by a telephone subscriber is accurately andpositively recorded and indicated in order that said subscriber may haveafpersonal check'cn the calls made by him. Theconstruction and use ofthe invention will bei explained with the aidof theattached drawingsshow.- ing same in its idle position. In said drawings Fig. 1 is asectional perspective view taken from the right hand rear corner of atelephone box-in said view the counter Wheels and related members areremoved for sake of clearness. Fig. 2 is a side elevation of Fig. lVshowing said counter wheels in position. Fig. Sis a perspective view ofsaid wheels `as carried on the swinging yoke. Inthese three views theinvention sdrawn to anv enlarged scale. Fig. t is yaA broken front view.of'the door of the telephonebox with its thereon carried' members.

vReferring to said drawings the device as a unit Ais fitted on a. baselplate a whereby it is enabled to be neatly housedV within the telephonebox al, Y fEngagea'bl'e with the telephone switch hook l) is adownwardly extending and rectangular shaped lever b1 having an upwardreturn portion Z22-said lever being guid-` ablyheldl by slots and pinsbfi within the .double cheeked frame b4. The horizontal portion b5 ofsaid lever b1 is forinedat an oblique angle to engage with a terminal,block c formed on a horizontal slidable bar 01 andwhen the switchhookis depressed bythe weight ofthe telephone: receiver a Y projectinglinger 'c2 Yof .the saidv slide bar V4c1 makespushing Contact against apawlcZ pivotally carried on the outside of the frame Z- -said pawl'being adapted to lhave locking. engagement lwith a'notchv 1 on theunderside of the plunger coto hold andy retain l saidV plunger Ae in itsinwardv position.

yOn said plungery c ispivotallycarried a fengageable with a lug f1'onfthe horizontal slidable bar c1 andby the". forward movement of latterbar, said pawl, f is brought into position to; lock a detent' gpivotally mounted as shown across the face of,V a swinging yoke g1mounted between the cheeks of the frame bi1 on a spindle'j held bysaidgcheelrs.

.'On the existing rotatable` dial hl of the telephone is formed aninwardly projecting locking said detent. On the spindle 'j are rotatablymounted a number of separate counter wheelsl as'j1 jz andl js eachhaving ten teeth-saidA wheels beingv positioned in sequence` torespectively A denotey values ofV unitsV tens hundreds7 and sof onl innumerical succession.- Each wheel isfmadc with a gap [c for the.purposes hereafter mentioned, and each wheelv is'also fitted-with a"spring `controlled retention pawl l and with a springcontrolled drivingpawlaslf,l2 7c3 ict-said driving pawls being integrally formed'in agroup andasaunit pivotally carried on the swinging yoke g1 the latter4bleing freely movable onthe throughspindle y'. These driving pawls areof steppedi for;- mation asA shown in ordert'o operate the counter'wheels in usual manner..

its full rotation its drivingV pawl as zdrops into the gap 7c thereforprovided thus allowing' the next succeeding neighbor pawl 7c3 to comeinto kdriving engagement with vthe next `or"tens wheel l succession. l

y The plunger e when' inwardly'pushed closes the transmitter circuit Vmthus allowing the vtelephone to be 'operative in orvmovement of the dialtfowing vto the pawl Y. so As soon as the"units wheel'y'1 has made jzand so on in numerical Y vvdinary manner; This plunger e `i's pushed ydetent g thus rendering the linger t'lfon the 'dial L iii-operative.V

To work the invention the receiver isremoved from its switch. hook Zithusfreeing the therewith engageable lever blfrom contact with theterminal block c of the slidable bar-c1: which action through the agencyof the finger@2 allows the pawl of..r the .plung- 'v er e to be ready'to function. The forward movement of theslidable bar c1 by its lug f1is disengaged from contact with the pawl y thus allowing latter to lockthe detent g across 4the-aceof the yoke g1.

The dial as the primary motive member thefcaller by finger actioninwardly pushes `which have been made.

the plunger e causing it to close the transmitter circuit m and belocked in such position bythe pawl CZ engageable with the notch d1 ofthe said plunger; consequently allowing the transmitter circuit fm tobecome operative and by such movement causing the call to be registeredon and by the counter wheels as jl 7'2 and jg. j y

`The detent g ofthe plunger as previously shown has been advanced acrossthe face Vor the yoke g1 by the initial movement of' the telephone dialand the'said detent now moving with thev plunger e ythereby causes theyoke g1, and thereon drivingpawls 7a2 7c3 7o* to radially move on thespindle which movement causes that driving pawl which is in engagementwith a counter wheel (or if more than one driving pawl is in engagementwith its wheel) Yto make one-tenth of a revolution and consequentlyindicate the call made or the aggregate number or' calls Upon replacingthe receiver on its hook the plunger e with lits, members by urgingsprings is released to the idle position ready for the next call eitherto be made or answered. y

The' call or aggregate number of calls are recorded and readable on thecounter wheels through a window 29 therefor provided in the door p1 ofthe telephone (see Figs. l, 2 and 4). vThe yoke g1 is returned to theidle position by spring r suitably anchored to said yoke and to theframe.

In using this invention a subscriber who is-called cannot transmit untilhe has pushed the plunger e into its circuitclosing position as m1 asthe dial h notV having been moved the detent gV remains idleand thislast mentioned movement of the plunger does not record a call.
